"Your case has been accepted and routed to the USCIS California Service Center for processing. Within 7-10 days by standard mail you will receive your official Receipt Notice (Form I-797) with your Receipt Number WAC*********. With the official Receipt Notice (Form I-797) you may visit www.uscis.gov where you can check the status of your case using My Case Status. We suggest you wait until you have received your Form I-797 before checking My Case Status."
What exactly does this mean? Is it time to celebrate or can it still be denied?
